What does this mean for Sony?
Well, this means that at any-and-all Street Fighter tournaments that take place in the future that include Street Fighter V will have to be hosted on PS4s, rather than the usual favourite, the Xbox 360. This could also potentially–although I would not hold my breath–lead to fight-sticks being manufactured for the PS4.
These factors combined may cement Sony’s exclusivity for the foreseeable future; until, at least, Microsoft pull something big out of the bag.
